T0 (MZ 1071/0771/ it mfcty/ concern: v

Be it known that I, THOMAS K. BAKER, a citizen of the United States ofAmerica, and a resident of Minneapolis,vin the county of Hennepin andState ot' Minnesota, have invented certain new and 'useful Improvementsin Coffee-Makers, ot' which the following is a specification.y

My invention relates to coffee-makers, and more particularly is animprovement upon the codec-maker described in my application for LettersPatent, Serial No. 81,810, tiled November l1, 1901.

The object of my invention is the production of a simple and efficientcoffee-makerV (adjustable to coffee-pots of varying styles) in which thestrainerniay be easily and quickly attached, so as to produce a tightjoint be.- tween the wall ofthe open end ot' the vessel and thestrainer.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of my im proved cotfee-maker,shown partly insection. Fig. 2 is a perspective view of the holder for the strainer.Fig. 3 is a perf spective View of the holder with the strainer attached,part of said strainer being broken away to show the split ring by whichit is adjusted to the holder. Fig. 4 is a sectional view of the valve inthe bottom of the coffeemaker.

In the drawings, letA represent the coiee-- maker, which is formed withthe open tapering end B and provided ,with the circular flange 2, Whichsurrounds the opening or mouth of the vessel. The handle 3, threaded at4 in the side of the vessel, is shown partly broken away. This handlemay be detached by unscrewing for convenience in shipment and use of thecodec-maker. The strainer O, made of cloth or other suitable material,as shown, is circular in horizontal cross-section and tapers slightlyfrom itsopen to its closed ends. The open end of the strainer is adaptedto t inside the flange 2 in the open end ot' the vessel and is providedwith the split spring ringer collar 5 for attaching the strainer to theholder D, as shown in Fig. 3. This holder is a skeleton frame otsuitable shape to fit snugly inside and hold the strainer open. Theholder is provided with the collar 6, to which the handle 7 is attached.The

4'of the'tlange, as shown in Fig. 1.

wire loop S atvthe base of the holder is attached to the collar by theside arms 9, which are joined at 10 and 1l, respectively, to the loopand collar.

The valve E (shown in the drawings) is automatic in action and consistsof the stein11n, sliding through the opening l2 in the inner cylindricalprojection 13 on the bottom 14 of the coffee-maker. The valve-head 15 isattached to the upper end of the stem 11 and is seated on the projection13. The stem is provided with the passage-way 16, (see Fig. 3,) which isadaptedto receive air into the vessel when inverted. The lower end ofthe stem is provided with the washer 17, Which is att-ached by screws 18and adapted to abut against the .shoulder lt). The head and washer limitthe movement of the stem. The Washer is provided with the opening20,which registers with the air passage-way 16. The stem slides when thevessel is tilted or inverted, so that the upper end 2l of thepassage-way A16 projects beyond the shoulder 22 ofthe wall 18. The valveis adapted to reduce the danger of clogging by the cofeegrounds.

Vhen the maker is in use, the holder is lslipped into' the strainer, asshown in Fig. 3,

and holder'are then attached to the mouth of thejvessel bythe handle 7and the open end of the strainer pressed down over the outside It isobvious that vwhen the coffee-maker is in use the coffee may be preparedby any of the usual methods-t'. e., boiling water may be poured uponpulverized coffee or either pulverized or granulated codee may be boiledin the vesseland that the strainer may be adjusted to the maker afterthe codec and Waterare in the vessel. After the coiee has been made andthe strainer and holder closely fitted in the mouth of the vessel, asshown in Fig. 1, the vessel is tilted or inverted with the tapering endin the coffee-pot, and the cottee fiows into such receptacle ready foruse. When the coffee is emptying from the maker, the coffee-groundsgather on the strainernear the mouth of the vessel, leaving the innerend of the strainer practically free from grounds, and thus expeditingthe Lflow of the coffee.

ISO

By constructing the strainer and holder so that the larger end of thestrainer enfolds the outer surface of the ange 2 and the collar 6 of theholder presses the strainer against the inside of said flange atightjointis produced which prevents the coiee from leaking around theange. To remove the strainer, its open end is sprung over the upper edgeof the collar 6 to the position shown in Fig. 3. The holder and strainerare then lifted from the mouth of the receptacle by the handle 7.

Having described my invention, What I claim as new, and desire toprotect by Letters Patent, is-

1. A device of the class described, consist# adapted to eni'old saidflange, and means for holding said strainer in the mouth of the Vessel.

3. A coffee-maker closed at one end and terminating in an opening at theother, a flange surrounding said opening, an automatic valve in saidclosed end, substantially as shown and described, a strainer surroundinga holder in said opening, an expansible ring at the open end of thestrainer adapted to clasp the strainer and outer surface of said flangetogether. l

4. A coffee-maker consisting of a vessel closed at one end and taperingat the other to an opening, a valve in the closed end of said Vessel, atapering strainer reversed in said opening, and means, for attachingsaid strainer in said vessel, consisting of a skeleton holder Within thestrainer and split ring around the open end thereof.

In testimony whereof I have signed my name to this specification in thepresence of two su bscribing Witnesses.
